[0002] The bag-making machines on the market now, such as vest bag machines, flat bag machines, roll-to-roll machines, biodegradable bag machines, etc., use roll film to cut into strips of film during production, and every few or dozens of films are bundled, and then the whole bundle of products or the whole bunch of products need to be neatly arranged, and then the whole bundle of products is carried out to the next process, and then punched or placed neatly. The existing machines all use shafts and retaining rings to fix the position of the film. Every time other specifications are changed, the retaining rings on each threading shaft need to be manually moved to fix the path of the film and prevent the product from moving left and right to produce scrapped products, which is troublesome, time-consuming and labor-intensive; in addition, the machine operator needs to always pay attention to whether the product is offset or blocked by the retaining ring to produce a folding phenomenon, as well as the uneven products produced by the left and right swing of the product. If the product is offset beyond the range, it will become a defective product and cause material waste. Therefore, it is necessary to design a new film correction device to solve the above technical problems. Utility Model Content

The deviation rectifying mechanism is installed on the frame 10 and includes a deviation rectifying component and a deviation detector;

[0028] The deviation rectifying component includes a lifting mechanism 2, a connecting seat 3 and a deviation rectifying roller 5. The lifting mechanism 2 and the connecting seat 3 are respectively arranged on both sides in the width direction of the film 9. One end of the deviation rectifying roller 5 is connected to the connecting seat 3. Specifically, the deviation rectifying roller 5 is hinged to the connecting seat 3, and the other end of the deviation rectifying roller 5 is connected to the lifting mechanism 2. The lifting mechanism 2 is used to control the lifting of the end of the deviation rectifying roller 5 away from the connecting seat 3; during use, the film 9 bypasses the deviation rectifying roller 5 and contacts its top;

[0029] The deviation detector includes two deviation rectifying sensors 4. The two deviation rectifying sensors 4 are respectively arranged on both sides in the width direction of the film 9. Each deviation rectifying sensor 4 is provided with a driving device, and the driving device is used to drive the deviation rectifying sensor 4 to move along the width direction of the film 9, so that the position of the deviation rectifying sensor 4 can be flexibly adjusted according to different film widths.

[0030] In this embodiment, it should be noted that the lifting mechanism 2 includes a lifting seat 11 and a lifting driving motor 12. The lifting seat 11 includes a fixed seat 13, a guiding column 14, a lead screw 15 and a lifting table 16.

[0031] The lead screw 15 is vertically arranged, the lead screw 15 passes through the lifting table 16 and is threadedly connected thereto. The output shaft of the lifting driving motor 12 is in transmission connection with the lead screw 15. The end of the deviation rectifying roller 5 away from the connecting seat 3 is hinged to the lifting table 16;

[0032] During use, after the lead screw 15 is driven to rotate forward or backward by the lifting driving motor 12, the lifting table 16 can be driven to move up and down along the guiding column 14. During the up and down movement of the lifting table 16, the end of the deviation rectifying roller 5 away from the connecting seat 3 can be driven to rise or fall; when the end of the deviation rectifying roller 5 away from the connecting seat 3 rises, the deviation rectifying roller 5 will cause the film 9 to shift towards the side close to the connecting seat 3, so as to adjust the position of the film 9; when the end of the deviation rectifying roller 5 away from the connecting seat 3 falls, the deviation rectifying roller 5 will cause the film 9 to shift towards the side away from the connecting seat 3, so as to adjust the position of the film 9.

[0033] Further, the driving device includes a slide rail, a slide table and a driving motor. The deviation rectifying sensor is arranged on the slide table. The deviation rectifying sensor 4 adopts an ultrasonic deviation rectifying sensor.

[0034] The slide rail is arranged along the width direction of the film 9, the slide table is slidably connected to the slide rail, and the driving motor is used to drive the slide table to slide back and forth along the slide rail.

[0035] The technical effect achieved by this embodiment is as follows: by setting an offset detector, it is possible to automatically detect whether the film 9 is offset during use, and each correcting sensor is provided with a driving device. During use, the position of the correcting sensor can be flexibly adjusted according to the width of the film 9, and the adjustment is more convenient; by setting a correcting component, the correcting component includes a lifting mechanism 2, a connecting seat 3 and a correcting roller 5. During use, the height of one end of the correcting roller 5 is adjusted by the lifting mechanism 2, so that the film 9 can be controlled to move a certain amount along the length direction of the correcting roller 5, thereby adjusting the position of the film 9 and correcting the offset of the film 9; the offset detector and the correcting component are used in conjunction with each other to automatically detect and adjust the position of the film 9, so that when the position of the film 9 is offset, it can be corrected in time to avoid the production of defective products.
